Desert bighorn sheep in Valley of Fire State Park, Nevada, United States

Rocky relationship. Bighorn sheep in Valley of Fire State Park, Nevada, United States

Nature's desert navigators—desert bighorn sheep—are a marvel to watch, effortlessly scaling cliffs and navigating rocky terrains with grace. Native to North America, these sheep are known for their distinctive curled horns, which can weigh more than 10 kilograms. Rams use their massive horns in intense head-butting contests. During these battles, males hurl themselves at each other in charges of over 30 kilometres per hour. Ewes, on the other hand, tend to keep things more low-key, forming smaller groups with their lambs. Adapted to the desert environment, bighorn sheep can go long periods without water, relying on moisture from plants to survive.

Valley of Fire State Park, seen in today's image, is one of the best spots in Nevada to observe these desert dwellers. This park is named for its fiery red sandstone formations that seem to glow under the sun. Beyond its natural beauty, the park holds deep historical significance, with petroglyphs left by ancient Indigenous peoples. It has also earned a place in pop culture as a filming location for scenes from 'Star Trek Generations.' Keep an eye on the rocky outcrops during your visit—you might spot a bighorn sheep observing you.
